--------------------------------
Summary: NPE may be thrown and logged during WS-RM's retransmission
Key: CXF-5546
URL: https://issues.apache.org/jira/browse/CXF-5546
Project: CXF
Issue Type: Bug
Components: WS-* Components
Affects Versions: 2.7.9
Reporter: Aki Yoshida
Assignee: Aki Yoshida
While a message is being retransmitted from a client (RM-Source) from its
retransmission queue, the corresponding message might be acknowledged and its
resource released at the client. And in this case, an NPE will be thrown during
the resending of the message.

Note that this issue is about handling this case gracefully to avoid throwing
an NPE. The issue itself does not break the delivery guarantee semantics as the
resend is failing because the message has been acknowledged.
